Jeez, I could have sworn I used that feature before. Last night, I was trying to get to the root of a bug in someone else's network library and wanted to mark all the uses of a particular variable so that I could quickly jump around the code and see where it gets modified. Find & Mark All would have eased things, but even better would be my previous suggestion of adding a FIND toolbar like Firefox. With a feature like that I could have typed the variable name in the find toolbar, then just clicked a "Find next" button to jump to the next instance without ever leaving my code.
